Alt has commenced a 3,500 metre RC drilling program on Friday
The Company will be drilling several deposits and new prospect areas during this current program of RC drilling, including the Single Fin prospect which is south and along strike from the Boags open pit at
Alt staff have spent several months reviewing historical data from work undertaken by
MT IDA PROJECT, TIMONI MINERALISED TREND
The TMT area is located approximately 6 kilometres north-east of the
The TMT is considered to be highly prospective for high grade gold mineralisation. Known deposit styles include high grade shear/vein hosted gold and base metal sulphides. Historically over 300,000 ounces of high-grade gold has been mined from the various mines in the Copperfield/Mt Ida area4. Numerous brownfields exploration opportunities are present with the potential to make new discoveries.
The TMT is a structure located adjacent to the western margin of the Copperfield Granite, and sits to the east of, and parallel to, the Bottle Creek Trend. The structure hosts the Copperfield Mining Centre. Mineralisation along the TMT generally comprises narrow, high-grade quartz veins hosted predominantly by mafic volcanics (amphibolites), ultramafic intrusions and anorthosite. Gold mineralisation is primarily associated with NW-SE striking shear zones, that contain mineralised lenticular quartz veins. Mineralisation is observed in the form of free gold, pyrite, pyrrhotite, galena and minor amounts of chalcopyrite and sphalerite, hosted within a strongly developed carbonatebiotite wall rock alteration envelope.
The Ballard Shear zone is located in the east of the Mt Ida area and is interpreted to be the northern continuation of the Zuleika Shear. The Ballard shear hosts the Company's Quinn's, Tim's Find, Spotted Dog and the newly discovered Shepherds Bush deposits. The Ballard Fault is noted by a series of shear zones, trending north-south transecting the eastern portion of the Mt Ida area and is approximately conformable to stratigraphy.
The Ballard Shear transects a series of mafic and ultramafic flows with associated interflow sediments. Conformable dolerites and gabbros dominate, with lesser occurrences of pegmatite and aplite intrusions. The shear zone is observed at surface as an outcropping chert unit. Drilling in the Ballard shear zone has intersected silicified sediments, iron-rich rocks, graphitic shales and calcareous schists with abundant sulphides. Gold mineralisation at surface is commonly seen in gossans and hosted in pyrite, arsenopyrite and pyrrhotite bearing quartz veinlets within the shear.
In the Mt Ida area, a folded greenstone belt forms a southerly plunging antiform, called the Kurrajong Anticline and the Copperfield Granite occurs within it's fold axis. The anticline is interpreted to be a isoclinal fold plunging at a low angle to the south. The fold has been overturned to the east-north east. This model is supported by the sub-vertical dips measured on the eastern Mt Ida limb and western
TMT EXPLORATION DRILLING
The company has delivered several priority drill targets for the Mt Ida TMT. These targets have been generated by an in-depth review of all available historical data, including geophysics, structural works, geological findings and geochemical analysis. Alt considers the TMT which incorporates several of the historically mined Timoni lodes, the TMT may extend into the Company's tenements to the south east and adjacent to the old Timoni mine. Based on the review of all available historical data the Company has delivered several priority drill targets for the Mt Ida TMT, based on multi layered magnetic, structural, geological and geochemical results. The Company intends to test several of these projected load extensions with RC drilling.
TIMONI MINERALISED LODES
Historical loads of interest adjacent to Alt's tenement boundaries and within target areas generated by the Company over the past few months include the Unexpected, Federation, and Baldock lodes.
Dave and
The Dave Lode was discovered during the early development years of the Copperfield camp (Raymond, 1898). The Baldock Shoot is located to the south of the Whinnen lode towards Alt's tenement E29/0921. The upper extent of the Baldock shoot is 100m deeper than the Whinnen Shoot, it is interpreted to gently plunge to the north and remains open at depth. A common feature of the Dave, Whinnen and
The Unexpected Lode
The Unexpected load dips steeply to the west, it is hosted in a NW-SE striking ultramafic package of rocks and is situated towards the southern end of the Timoni mine area. Historic production records found in the Swan Gold Prospectus dated
The Federation Lode
The Federation (Fred) lode is also hosted by Timoni amphibolite, some 300m west of the Timoni lode. Historic production records found in the Swan Gold Prospectus dated
